I have been reading posts about charge techniques and usage to preserve the battery life but its often inconclusive and comes with different opinion. Even Apple do not have a proper usage/charge guide to maintain battery lifespan. Therefore, I have decided to conduct this study and perhaps produce a certain conclusion on what is the best charge technique to maintain the battery life of our Macs. Please fill in the following template and a final conclusion will be produced once we've received enough inputs. Use software like Coconut Battery to retrieve the relevant information required by this study. MacBook Model (type,year,unibody): Charge Cycle: Age of your Mac: Battery capacity (current-original): Health in %: Did you calibrate your battery on your first use?: Do you calibrate your battery frequently? (daily/weekly/monthly): Do you use your MacBook as a (desktop/travel only/mixed?): Do you keep them on charge in any of the above usage? (yes/no) Do you only charge your MacBook when the battery is: (most common practice) -less than 70% -less than 50% -less than 10% -When it is possible -All the time (plugged at all time) Do you use your MacBook heavily?: (average hours daily) Do you think if you're applying any special technique that help you retain your battery life?
